Specification of Letters Patent. Application filed July 3, 1909.

Patented Feb. 1, 1910.

semi No. 505,792.

To all whom it may concern:

Be it known that we, GUs'rAr OLSON and JOHN PERssoN, subjects of King of Sweden, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hinges, of j which the following is This invention relates to hinges, and has for its object to provide improved means for adjusting one of the hinge" plates with respect to the other, in order to vertically adjust the `door or other swinging parts carried by the hinge. This object is effected by roviding an inclined shoulder at the top' of the knuckle of one hinge leaf, said incline extending in a spiral around the pintle, and upon this shoulder is mounted a sleeve or collar which is provided with an internal inclined shoulder which rests upon sai shoulder, and by turning the collar it is raised or lowered, and it is held in position by means of a ratchet at the shoulders.

Tle invention is illustrated in the accompanying drawings in which Figure 1 is a front elevation of the hinge; Fig. 2 is a perspective view of one hinge member; Fig. 3 1s a section of the collar; Fig. 4. is an end view of the collar, showing the ratchet.

Referring specifically to the drawings, G indicatf one ,hinge l,ea or member and? the other, t e former being preferably the fixed butt which is, attached to the door jamb or post. This member has a knuckle 8 and a pintle 9 projecting upwardlyl from the knuckle. The top of the knuckle is made -with an inclined shoulder 10, extending spi rally around the pintle, and a single tooth 11 is made on the incline to engage the ratchet of the collar. This collar 10 fits over the pintle and is counterbored at its lower en d to receive the top of the knuckle 8. The formed by the counter -bore, within the collar, is inclined or mad spiral complementary to that of the shoulder 10, and said shoulder 12 is provided with a series of ratchet teeth 13 arranged to engage the tooth 11 at any desired point. The collar has holes 15 to receive a pin by which it ma be turned.

The knuckle of rests on top of the collar, and is free to swing on the pintle as the door is opened or closed.

\ lar may be turned,

a specification. i

are member 7 is plain and To adjust the member '7 vertically the coland will ride up the in clined shoulder, and the ratchet will engage the tooth at the desired point to prevent back slip of the collar. By turning the collar completely around, it will drop down to originalposition. A door or gate may thus be hung and thenthe hinge adjusted to fit. It will also be found particularly useful for #raising old doors after they settle.l This can be clone in an instant -by simply turning the collar a notch or two. This can be done without removing the door or separating the hinge as when washers or the like are used. Thecollar can be made of harder metal than the hinge leaf, so as to resist wear.

Ve claim: j,

1. A hinge having an inclined shoulder at the end of the knuckle of one of its members, around the pintle, a collar on said pintle, having an inclined shoulder resting against said shoulder, whereby the position of the collar will be varied as it is turned one way or the other, and upon which collar the knuckle of the other hinge-member rests, and means to hold the collar in usted position.

Q. A hinge having a shoulder at theend of the knuckle of/one of itsmelnbers, in a spiral around the 'hinge pintlewithla projection on said shoulder, and a collar rotatable for adjustment on said pintle, and having an inclined shoulder resting upon said shoulder and provid ed with a ratchet to engage said projection and vprevent back slip oft e c ar theknuckle of the other hinge mei lien reisting on said collar when the hinge members are assembled. 3. A hinge comprising tyvo members with knucklesand a pintle, one member having an incline extending around the pi'ntlc, a collar on the pintle between the' knuckles andresting against said incline and arranged to ride up ordown positions of the members, and means the collar in adjustednposition.

In testimony whereof, we aliix. our signatures in presence of two witnesses.
